Add support for boolean variable type to better handle if statements. #5

In the README, the following files are suggested as examples:

boilerplate.yml

variables:
  ...
  - name: ShowLogo
    prompt: Should the webiste show the logo?
    default: true

index.html

<html>
   ...
  <body>
    ...
    {{if .ShowLogo}}<img src="logo.png">{{end}}
  </body>
</html>

But as written, this example will always render the <img> tag because boilerplate doesn't yet support any variable type other than string. In this case, a boolean type would allow this to work.

As a string, the only way to get the if statement to be false is for .ShowLogo to be empty, which requires that no default value be defined.

I'm going to close this as a duplicate of #9.

FWIW, the current work around for booleans is to compare the variable to the string "true". E.g.:

{{ if eq .ShowLogo "true" }} 
  (do something)
{{ end }}
